Azfurtherrobiectroftmy invention is to provide a simplified arrangement having the above characteristics.

With .these. andother.

Figure 3 is a sectional view taken along the lines 3-3 of Figure 1.

My invention contemplates principally the provision of a hydraulically operated manure loader which also can be converted to other types of loaders, and whereby certain elements are so arranged that the lifting effort required can be adjustably positioned to allow for lighter or heavier loads.

I have used the character Ill to designate a standard tractor having the forward wheels II and the rear wheels I2, and the character l3 designating the rear seat, and the character It the rear axle. The rear power take-off shaft is indicated by the character l5 and is connected at It to a further shaft I! which drives a suitable pump 18 secured to the drawbar IS. The pump I8 is controlled by means of the rod 20, and communicating with the pump l8 at 2| is a tube 22 which communicates at 23 to a Y-connection 24 which branches into the pair of flexible tubes 25 which are connected at 26 to a pair of hydraulic cylinders 21.

A pair of brackets 28 are attached at 29 to openings in the tractor frame, the brackets 28 including openings at 35 whereby the single rod 3| (see' Fig. 3) can be inserted therethrough beneath the tractor frame, the rod 3| passing through spacers 32 and also passing through the 2. openings .33: at thelower :endswofwthe :crlindersfislt the :nuts 3mservingyto retainutheihlidraulic "Qyliire ders, the hydraulic cylinders thus being pivotallst securedrat-theirslowerends:

Pivotally attached at 52 to the beams 45 is a manure loading bucket 53 having the prongs 54 and including the member 55 which can be tripped by means of the mechanism 56 and 51 which is operated by means of a rod or cable 58.

The beams 45 include marking at 59 and 60 for indicating proper positioning of the U-bolts as desired.

It will now be seen from the foregoing arrangement that when it is desired to lift manure, etc., the arrangement is positioned as shown in the solid lines in Figure 1, with the pump l8 forcing the oil through the pipes 25 into the cylinders 21 thereby raising the entire arrangement to the position shown, after which the bucket can be tripped for unloading. The hydraulic oil supply can be obtained from the tractor itself or from any suitable tank, and for lifting the lighter loads the arrangement is positioned as shown.

In many instances however, it may be desired to cause the arrangement to be operated as a hay loading arrangement or in some other similar, capacity, the hay rake being indicated by the dotted lines. For lifting these heavier loads it is desirable to place the lifting effort or the cylinders forwardly on the tractor in which instance, the bracket is moved forwardly to the dotted pomade in the usual openings, and the bolts 41 are loosened, the rods 50 and are removed, and the members 4| are placed in the dotted position shown in Figure 1 with the U-bolts 46 being retightened in this new position, and with the rods 50 and 5| being then reversed, the rods being made the exact length for this purpose.

The lifting effort is then directed forwardly towards the heavier load on the unit El thereby fully taking care of the requirements necessary. By virtue of this construction then, the load operated by the tractor will not be excessive for the lighter load conditions, thereby requiring less power and fuel and resulting in the economies desired, and for the heavier loads the lifting eifort will be thereby minimized since the leverage is applied at the more appropriate location.

It will be understood of course, that any spacing can be effected as desired consistent with the above structure.

It will now be seen that I have provided the advantages mentioned in the objects of my invention with further advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. A manure loader comprising a pair of arms, hydraulic means for raising said arms including a pair of hydraulic cylinders pivotally attached to a tractor to which said arms are pivoted, said cylinders having pistons therein, rods attached to said pistons, an inverted U-shaped brace member attached to said arms, bearing members attached to said rods receiving the horizontal portion of said U-shaped bracing member, means for positioning said bracing member at selected positions along said arms for providing greater lifting eifort to said arms, rods attached to said bracing member and said arms, said rods adapted to provide further bracing means, said rods being of such lengths so that upon adjustable positioning of said bracing member, said rods can be interchangeably attached, brackets attached to the tractor, said cylinders being pivotally attached to said brackets, means for adjustably positioning said brackets at selected positions to the tractor.

2. A manure loader comprising a pair of arms, hydraulic means for raising said arms including a pair of hydraulic cylinders pivotally attached to a tractor to which said arms are pivoted, said cylinders having pistons therein, rods attached to said pistons, an inverted U-shaped brace member attached to said arms, bearing members attached to said rods receiving the horizontal portion of said U-shaped bracing member, means for positioning said bracing member at selected positions along said arms for providing lifting effort to said arms, rods attached to said bracing member and said arms, said rods adapted to provide further bracing means, said rods being of such lengths so that upon adjustable positioning of said bracing member, said rods can be interchangeably attached, brackets attached to the tractor, said cylinders being pivotally attached to said brackets, means for adjustably positioning said brackets at selected positions to the tractor, means for adjustably securing said U-shaped member to said arms including plates secured at the lower ends of said member, U-bolts receiving said arms and attached to said plates.
